1. Summary:

Updated udev packages that fix a security issue are now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

The udev package contains an implementation of devfs in userspace using
sysfs and /sbin/hotplug.

Richard Cunningham discovered a flaw in the way udev sets permissions on
various files in /dev/input. It may be possible for an authenticated
attacker to gather sensitive data entered by a user at the console, such as
passwords. The Common Vulnerabilities and Exposures project has assigned
the name CVE-2005-3631 to this issue.

All users of udev should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
